An important issue regarding DNA electrical conductivity is the electron (hole) transfer rate. Experiments have found that this transfer rate involves quantum mechanical tunneling for short distances and thermally activated hopping over large distances. The electron (or hole) tunneling probability through a molecule depends on the length of molecule L, as e(-beta(E)L), where the tunneling betaE...

BACKGROUND Metrafenone has been used in Europe in integrated pest management programmes since 2006 to control powdery mildews, including Erysiphe necator. Its exact mode of action is not known, but it is unique among fungicide classes used in powdery mildew management. Recently, resistance to metrafenone was reported in Blumeria graminis f. sp. tritici. In this study we investigated metrafenone...

One genus and species are synonymized in the tribe Empoascini of the subfamily Typhlocybinae. Bhatasca Dworakowska, 1995is a junior synonym of Alebrasca Hayashi & Okada, 1994, Bhatasca rectangulata Qin & Zhang, 2011is a junior synonym of Alebrasca actinidiae Hayashi & Okada, 1994. Furthermore, Bhatasca expansa is (necessarily) transferred to the genus Alebrasca.

The prototypical fibroblast growth factor receptor (FGFR) extracellular domain consists of three Ig domains (D1-D3) of which the two membrane-proximal D2 and D3 domains and the interconnecting D2-D3 linker bear the determinants of ligand binding and specificity. In contrast, D1 and the D1-D2 linker are thought to play autoinhibitory roles in FGFR regulation. Here, we report the crystal structur...

A powdery mildew was found associated with the coastal wattle, Acacia sophorae, at Tullymorgan, in northern New South Wales, Australia. Morphological characterisation identified it as belonging to genus Erysiphe, while internal transcribed spacer (ITS) sequencing and phylogenetic analysis confirmed Erysiphe quercicola, a pathogen worldwide distribution broad host range. This is first record of ...
